Heraeus 6-element 3QNY/Cr/Co/Cu/Fe/Mn/Ni-V (3QNYCrCoCuFeMnNi-V) Hollow Cathode Lamp, Chromium Cr + Co + Cu + Fe + Mn + Ni, 37 mm Varian/Agilent/GBC coded, 4pin - 80018211

Heraeus 6-element 3QNY/Cr/Co/Cu/Fe/Mn/Ni-V (3QNYCrCoCuFeMnNi-V) Hollow Cathode Lamp, Chromium Cr + Co + Cu + Fe + Mn + Ni, 37 mm Varian/Agilent/GBC coded, 4pin

Hollow cathode lamps (HCL) are discharge lamps designed for use in Atomic Absorption (AA) instruments. They consist of a cathode made from the element of interest, an anode and an inert filler gas contained in a glass envelope. Noblelight offers the widest selection of single- and multielement coded / non-coded in low and high-current, 37 mm and 50 mm lamps in the industry.

Noblelight hollow cathode lamps are available both for OEMs and as a replacement lamp by discerning users the world over. The range includes standard lamps and data-coded versions for PerkinElmer and ThermoFisher atomic absorption spectrometers.

Multi-Element Lamps

Heraeus manufactures the largest range of multielement lamps offering only those combinations which provide suffi cient intensity and an acceptable lifetime for each element with no spectral interference. Multi-element hollow cathode lamps are available with two to seven different element combinations. These are particularly useful for carrying out routine analysis on a number of different elements in the same sample, such as alloys. Multi element lamps are inevitably a compromise in which energy levels will be lower than single element lamps and hence noise levels may be higher. This may limit ultimate detection levels, single element lamps being preferred wherever sensitivity is an issue.

Standard 37 mm Lamps

37 mm hollow cathode lamps are suitable for most commercial atomic absorption instruments. Standard lamps may also be used in computer controlled spectrophotometers which are designed to take coded lamps as these instruments normally have the facility to be set up manually. Manual setting up of lamp current, wavelength, slit width, gas conditions and burner height takes only a few moments and allows the operator to set the optimum conditions for each particular analysis, which can be stored and recalled when required. Indeed in many cases the instrument will set default conditions for these parameters on entry of the element. Whilst these parameters are generally suitable for a particular element, they may need fine tuning to suit the specific analysis being carried out.
